GARDNER H. STONE, OF JAMESVILLE, NEW YORK, ASSIGNOR OF ONE-HALF TO ELLISM. MOOHESNEY, OF SYRACUSE, NEW YORK.

HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 725,792, dated April21, 1903.

Application filed January 28,1901. Serial No. 45,096. (No model.)

To all 71/77/0772 it may concern.-

Be it known that I, GARDNER H. STONE, of Jamesville, in the county ofOnondaga and State of New York, have invented certain new and usefulImprovements in Horseshoes,

of which the following is a specification.

My invention has for its object the prod uction of a horseshoe which iseconomically manufactured and is of such construction to that its calksare readily removed and replaced; and to this end it consists in certainnovel combinations and devices, as hereinafter fully described, andpointed out in the claims.

:5 Figure 1 is an inverted plan view of my horseshoe. Figs. 2 and 3 arevertical sectional views taken, respectively, on lines 2 2 and 3 3, Fig.l, the main part of the horseshoe being omitted in Fig. 8. Fig. 4 is anisometric view of one of the detached calks.

My invention consists of the main part A of a horseshoe, sockets B, andcalks C. The main part A is of the ordinary construction, its lower facebeing formed with substantially fiat toe and heel surfaces. The socketsB,

which are secured to said toe and heel surfaces, are here illustrated asprovided with openings b, extending through their top and bottom faces,and with longitudinal depend- 0 ing portions b, arranged between saidopenings and formed with lengthwise grooves 12 which are extendedthrough the'end faces of the contiguous portions of the sockets forpermitting the passage of the calks C. Said grooves 19 are substantiallyalined with the openings 1), and their side walls are formed withupwardly-diverging inner faces 19 substantially flat lower surfaces 17and flexible extremities b. The sockets B are each se- 0 cured inposition by fastening members b 12 engaged with the main part A andarranged in the openings b, the fastening members I) having their lowerfaces arranged substantially coincident with the upper faces of thecorresponding calks for permitting the calks to enter the grooves b andthe fastening members If having their lower parts extended beneath thecorresponding ends of the fastening members b. Said lower parts of thefastening members b also extend below the lower faces of the contiguousportions of the sockets B and form, essentially, depending fixedprojections of the sockets alined with the grooves If. The sockets B,although preferably formed separable from the main part A, may beintegral therewith, if desired. Said calks C are removably securedwithin the sockets B, being here illustrated as having their side facesformed with upwardlydiverging surfaces 0 c and longitudinalshoul- 6cders c c for respectively engaging the faces 5 and the surfaces 17 ofthe sockets B. The shoulders c 0' may, however, be omitted, if desired.One end of each of the calks 0 moves longitudinally through and out ofthe groove 1) for receiving said calk, being thereby extended beyond thecorresponding extremities of the side walls ofsaid groove 11 and isengaged with the lower part of the contiguous fastening member blwhichprevents endwise movement of the calk in one direction, and the otherend of said calk is preferably formed with engaging faces 0 whichdiverge toward its opposite end, are arranged at the inner side of theflexible extremities b of the side walls of said groove 17*, and areengaged by said flexible extremities b for preventing endwise movementof the calk in the opposite direction. The diverging engaging faces cymay also be omitted, in which event the flexible extremities b willengage the end face of the calk O.

- In the use of my horseshoe the calks are readily removed from thesockets B by driving said calks longitudinally between the flexibleextremities 5 which bend backwardly to permit the passage of the calks.A new calk is quickly placed in position, and when one end of said calkis engaged with the corresponding fastening member b the flexi- 9o bleextremities b are'bent inwardly into engagement with the faces 0 Theconstruction of my horseshoe will now be readily understood uponreference to the foregoing description and the accompanying drawings.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination with the main part of 10.0 a horseshoe, a removablecalk, a socket provided with openings extending through its top andbottom faces, and a longitudinal depending portion arranged between saidopenings and formed with a lengthwise open-ended groove for receivingthe calk, said groove being substantially alined with the openings,fastening members engaged with said main part of a horseshoe andarranged in the openings for securing the socket to said main part of ahorseshoe, one of the fastening members having its lower facesubstantially coincident with theupper face of the calk for permittingsaid calk to enter the adjacent open end of the groove, and the otherfastening member having its lower part engaged with one end of the call:for preventing endwise movement thereof in one direction, and meansengaged with the other end of the call: tot-preventing endwise movementthereof in the opposite direct-ion, substantially as and forthe purposeset forth.

2. The combination with the main part of a horseshoe, a removable calk,a socket provided with openings extending through its top and bottomfaces, and a longitudinal depending portion arranged between saidopenings and formed with a lengthwise open-end ed groove for receivingthe calk, said groove being substantially alined with the openings,fastening members engaged with said main part of a horseshoe andarranged in the openings for securing the socket to said main part of ahorseshoe, onelof the fastening members having its lower facesubstantially coincident with the upper face of the calk for permittingsaid call: to enter the adjacent open end of the groove, and the otherfastening member having its lower part engaged with one end of the calkfor preventing endwise movement thereof in one direction, and saidgroove having a portion of its wall flexible for engaging the oppositeend of the calk and thereby preventing endwise movement thereof in theopposite direction, substantially as and for the purpose described.

In testimony whereof I have hereunto signed my name, in the presence oftwo attesting witnesses, at Syracuse, in the county of Onondaga, in theState of New York, this 16th day of January, 1901.
